... in which case the immediate solution to the problem is to:

seek F, 0, 0;

immediately before the inner while loop (see seek).

To the OP:

But reading the same input file multiple times is a poor design. Reading from disk is order(s) of magnitude more expensive than reading from RAM. Much better to read the file once, storing its data in a suitable data structure, and then iterate over that data structure as needed.

BTW, some consistent indentation would go a lo-o-ong way towards making the code more readable (and the problem more tractable).

Hope that helps,
